You most likely have a problem with the defrost cycle. could be several things. Does it gurggle after you close the freezer door? No? Do you get a strong suction on the door immediately after opening the door? Longer than 30 seconds is not right. Defrost drain may be clogged. It drains defrosted water into the pan under the unit near the coil. Unplug with a light gauge wire and drain cleaner.

Drain may be clear, but heating coils may not be be working well enough. In a marvel of technology, a self defrosting fridge activates heating elements mounted on the cooling coils. A timer heats the elements hot enough to melt frost to water inside your freezer. Very efficient! This water runs out to a pan in the bottom and is evaporated.

Your water is not draining, clogging the drain, then backing up with every defrost cycle. check the drain. If clear, it is probably the circuit board controlling it.

Candy CSC 1745WE fridge freezer just started making a noise like the cooling fan is catching on something.This noise stops when you put pressure on fridge or freezer doors. Any ideas, many thanks.

If the defrost is not working then ice could be forming inside the unit. If that's the case then it will get worse as more ice forms and the unit eventually wont cool or will cool very little. Sometimes a panel or the fan blade isn't adjusted right and it hits something making noises. In the case you would have to pull the covers off inside the freezer .

My GE GDSS6KKXASS French Door refrigerator has frost/ice buildup on the back panel of the fridge, and it is especially bad around the holes in the panel. I can't tell where the water/moisture is coming...

The door seal is leaking. The air that circulates thru the fridge is where the moisture is coming from. Since it has to run more often to keep it at the right temp, the ice forms on the back. Replace the seal and the ice will disappear.

My refridgerator smells like fermented oranges. the smell is now in the water from the fridge and tastes like the bad smell. fridge is a side by side maybe 5 years old, don't know the brand right now....

This may be from the dirt that has accumulated on its drain or inner panels. Clean out the unit. In that way you can inspect the insides. Clean out every corner and drains. Make sure you check the coils at the back of the fridge. You will have to unscrew the panels inside to get to it. Check if there are balls of ice forming on the coils. There may be a leak, and the smell may also be from the freon.

The fridge part of the fridge freezer has a coating of ice forming at the back and it feels warm behind bottom right veggie tray

Sounds like the freezer/refrigerator circulating fan is starting to wear out, When the motor for this fan starts to wear out it does not supply enough circulation for the freezer and the refrigerator. The minimum cost to repair/replace this fan is around $300.00. The immediate solution is to unplug you unit for about four hours allowing the ice that has formed around this fan to melt. Or use a hair dryer to melt the ice, but be very careful not to melt the plastic.

Integrated fridge freezer growing iceberg..

problem could be one of two things.
insulation breakdown will cause an iceball to form.
if the compressor is failing, then frost line does not reach the thermostat poisition and compressor runs all time and an ice ball will also build up
in either case, not worth repair
